There are three sigma symbols, an upper case, a lower case and an end of the sentence case. The capital letter case is used as summation. The lower case is used to represent variance in statistics. The lower case is also used to represent stress in mechanics and physics. The end of sentence case is generally not used. Reference link: http://en.wikipedia.org/wiki/Sigma.
In statistics, n is usually used to mean the number of observations or measurements which you have. So n = 7 means you have 7 observations or meadurements.

Both. "Case sensitive" means that upper case and lower case characters are treated as different characters.

Since this is regarding statistics I assume you mean lower case sigma (σ) which, in statistics, is the symbol used for standard deviation, and σ2 is known as the variance.

n is the sample size.
Lower case N
# include <stdio.h> # include <conio.h> int main () { char a; printf("Enter the number"); scanf("%c", &a); (a>=97 && a<=122)? printf("\n\nIt is a lower case alphabet"):printf("\n\nIt is not a lower case alphabet"); getch(); getch();}

No element has a single lower-case letter as its symbol. Nitrogen has the symbol N.
Initial time is usually t-sub-zero, written as a lower-case "t" followed by a subscript "0", and final time is usually t-sub-n (lower-case "t" followed by a subscript "n").
